To all whom it may concern.' Y

yBe it known that I, 'BRUCE' C. WHITE, a citizen ofthe United States,`residin at New York, county of New York, and tate of New York, haveinvented certain new and useful Improvements in Pumps, fully describedand represented inthe following speciiication and the Vaccompanyingdraw# ings, forming a part of the same.

This invention relates to"` an improved pumpl mechanism, designed forpumping and supplying iiuids, and particularly for pumping'and supplyingink to the distributing cylinder or other portion Yof the inkf ingmechanism ofa printing press, assho'wn for instance in myco-pendingfapplication, Serial No. 38,528, iiledJuly 7, 1915, of whichthe present application is a division. "It 'is the specialobject of theinvention to provide a. novel and improved pump de* signed for pumpingHuid, as ink, so as to supply `the'fluid under pressure and in regulatedquantities. vAffurther object of the invention is to provide a pumpingmechanism .including a plurality of valveless plunger VVpumps vwhich canbe independently ad justedvso that the fluid may be supplied in varyingquantities by each ofthe pumps. '1 I/Vith these and other objects notspecifically referred to in view, the invention4 has been illustrated inthe accompanying drawings as employed with the distributing ap` paratusofaI printinginachine, though it will be understood that it may be usedin otherrelations and for pumping fluid other than ink.. 'i

For a' full understanding of the invention' a description of the samewill be given in connection with these drawings, in which Figure 1 is adiagrammatic plan view partly broken 'away and partly'in section of adistributing cylinder of a printinglma-- chine and the ink supplymechanism.v

Figure 8 is a vertical cross section on 'y the line 8-*8ofv Figures 6and 7'; and

Figures 9'and -10 are partial views similar to Figure 8, but showing'theoperative parts In the ydrawings .the invention is illus-` trated asused fory pumping ink, and is shown, furthermore, embodying'a .pluralityl` of pumps forvindependently supplying ink to different'sections orparts of the form.`

It ywill be understood, however, thatthis showing is-'onlyi-for thepurpose of illus! tration and that they improved pump mechanism "maybe.. usedy either' singlyy or u in multiple, depending on. the purposefor which it is'required, and may be used with devices or machines otherthan printi'ng'machines, and with fiuidsother than ink. y

In the presentapplication of the invention, inkis'supplied to adistributor C from groupsfof vink delivery nozzles arranged in|reservoirs F, which'fare kept partially filled with ink or otherfluid.Where, asin the present instance, inkis to. be supplied to' a printingmachine, aplurality of the pumps will beemployed; The pumps will,'however, be similar in construction and operated in ay similar manner, nomattei` what numberare employed, and the construction` and operation' ofa'plurality of these vpumps will bedescribed."

These pumps'. `asy shown, force the ink through the conduits or supplylpipes E, which;` areI packed in openings formed in the bottom of thereservoir. A single acty ing pump, having `vertically" actingA plunger10, is provided foreach desired section lof the for-m, usuallya column,`two parallel g rows of these pumps being shown,the pump chambers forthese pumps being formed in bars `11 extending lengthwise of thelreservoirF and united by cross'bars 12 to form a' frame open betweenthebars 11 to `receive shaft v15 carrying'.eccentricl, by-p GID whichthe frame, with its pump cylinders and plungers, is moved sidewise andthe plungers 10 reciprocated, the eccentric 14 securing this sidewisevmovement of the frame through action on yokes on cross bars 12 of themoving frame, and thev vertical movement through action on vertical bars15 mounted to slide vertically in these yokes, while held from sidewise-movement therein. These bars 15 form downward extensions of a bar 16extending longitudinally of the reservoir above the pumps and which hasarms 17 extending over the pump plungers 10 so as to eneage and operatethe latter on the downward movement ofthe plate bar 16. This bar 16 alsocarries arms 18 extending on opposite sides of the bar, which arms carrypivot shaft 19 on which are loosely mounted rock arms 20, one for eachplunger, having toes 21 extending inwardly under flanged heads 1 ofplungers 10, and these arms 2O are formed of a sleeve and enclosedsliding stem, so as to be eX- tensible and spring-pressed apart byspring 22, the sleeve having a head 23 numbered to correspond with thecolumn or section of the form supplied by its pump, and the sleeve beingprovided with a catch 2 adapted to engage teeth 3 for holding the rockarm in adjusted position, these teeth 3 being formed in the undersideofarms 24l projecting in opposite directions from central web extendingupward from bar 16, the arms 24 preferably being` made separately andsecured in slots in the web 25 by a cover bar 26, as shown. The endsofthe arms 24 are tied together by rods 27 with spacing sleeves betweenthe arms so as to form the parts. carried by bar 16 into a frame thatreciprocates vertically in the frame formed by bars 11 and cross bars 12and moves sidewise with the latter frame. 1' 4The shaft 13 be driven byand lsuitable means, but as shown is driven vby gear 28 andintermediate29 from gearA 30-on sleeve 31 loose on driving shaft 32 andcarrying disk 33 having handle 34 mounted therein, this handle 34having` a point 35 entering a recess in disk36 keyed to shaft 32,- so asto clutch disk 33 and sleeve 31 to the shaft for driving the pumps whenthe handle 34 is thrown into the position shown in Fig. 5, whiley byrocking handle 34 outward against its holding spring, sleeve 31 isreleased from shaft 32, and the pumps can then be run by hand at thespeed desired for testing, cleaning or repair, or cleaning fluid may rberun through the pumps and pipes, if desired. The driving shaft 32 may bedriven from the distributing cylinder or other part of the press by anysuitable gearing so as to secure the proper speed, or may be dirven byseparate motor, if preferred.

The ink is preferably maintained at. the

rasaose desired level in the reservoir F by float control, the inletpipe H being controlled by valve 36 under the control of float lever 37and iioat 38, which parts may be of any suitable construction.Circulation of ink from the side of the pump frame at which supply pipeH enters is provided for by passages 39 connecting side troughs 40 witha central trough 41, with which connect-s a drainpipe 42, provision thusbeing made for draining the reservoir from troughs 40, 41, in which anysediment or thickened ink will collect and for washing the reservoir byrunning water or cleaning fluid therethrough. The reservoir ispreferably provided with a hinged cover 43, as shown, by raising whichaccess is had to all the heads 23 of the adjusting arms 20 for varyingthe supply of ink to any column or columns of the form.

The supply reservoir F is kept full yto the required level by the iioatcontrol of branch pipes H, so that a constant suction supply to thepumps is thus maintained. The pump, chambers formed in blocks 11 and inwhich the pump plungers 10 move, are brought by eccentric 14 alternatelyinto connection with the reservoir 4on the upward or suction stroke ofthe plungers 10 and intov line with the ports in the reservoir bottomconnecting with pipes E for they downward or delive stroke of theplungers, and the' Vertical movement of the bar 16 and plungeroperating` parts carried thereby is secured in proper time by theeccentric 1 4. A measured quantity of ink is thus delivered by eachApump under fixed pressure at each stroke of the plungers 10. Thesevalveless pumps aid materially in assuring the proper action of thepumps and their delivery of a fixed quantity of ink, and avoid thedilii'- culties incide-nt to handling ink with valved pumps. y

As described above, the lift of each plunger 10 on the suction strokeisl determined by the position of its rocking arm 20 which determinesthe time of engagement of toe 21 with plunger head 1, and the positionof the arms-20 is readily adjusted by moving the numbered heads orfinger pieces 23 sidewise. i

f 1n Figures f6 to 10 there is. shown a slightly modified constructionof pumps and regulating means, the other parts of the apparatus beingthe' same as above described. In this case the plungers 1() and theblocks 11 containing the pump chambers of the two sets are actuated. byseparate eccent-rics, the two blocks .11 being connected by cross plates54 at opposite ends, which are vertically slotted to receiveslidingblocks 55 `carrying eccentric sleeves 56m which runeccentrics'57'on shafts 58, so that the rotation of the eccentrics movesthe bloc-ks 55, with the frame formed by plates 54 and bars 1l,

sidewise, and moves the blocks 55, with their eccentric sleeves 56,vertically. The pump plungers l0 carry yokes 59, the upper ends of Whichare threaded on adjusting screws having finger pieces 61 extendingupivard into convenient position for access When the cover is liftedland preferably held in any adjusted position by springs 62 engaging theknurled side of the linger pieces. The 'adjusting screws 60 carryheadsi63 engaging the eccentric rings 56 to raise the plungers 10 thelength of the suction stroke or lift of the plunger, the amount of inkdelivered thus being regulated by the position of the screws 60, whichdetermines the lift of the yoke's 59 `and plungers 10 by the eccentrics.The eccentric shafts 58 may be rotated by any suitable means, b-ut areshown as geared together by gears 64 operated by gear 65 on shaft 66,which in turn,-

is driven through bevel gears 67 vfrom driving shaft 68 outside thereservoir F, and actuated from the press or otherwise in any suitablemanner.

In this construction there is shown, also a convenient means for cuttingout a Whole page of the inking, or such part thereof as theconstruction'may be designed for, by a single valve, which arrangementalso is readily applicable to the construction shown in Figures l t-o 5,and above described. For this purpose each row of the conduits or supplypipes H connects with a circular valve chamber in which is mounted arotating valve 69 extending over the Whole row of conduits H, or suchpart thereof as desired, and accessible from outside the reservoir forrotation, as by the squared head 70, shoivn in Figure 7. These valves 69have transverse ports 7 and the bottom plate of the reservoir F isprovided ivith tivo passagesv 8, 9, one connected With the pump chamberand the other with the reservoir, so that by turning a valve 69 into theposition shown in Figures 8 and 9 the pumps in the rovv corresponding tothe valve Will deY liver ink from the chamber through ports 8, 7, intothe conduitsior supply pipes I-I, and by turning the valve into theposition shown in Figure 10, the plumpsof its rou1 ivill be Clo-sed topipes H, and the ink be circulated through ports 8, 7, 9, from the pumpto the reservoir on the discharge stroke. The simple rotation o-f avalvev69, therefore, will cut out a page, or such portion of theinkingas the apparatus may b@ designed for, Without interfering With theadjustment of the separate pumps.

The operation of the construction shown in Figures 6 to l0 will besubstantially the same as that described in connection with Figures l to5, except as will be understood from the drawings, so that no furtherdescription of o-peration is required.
